Synchro Single Block with Becket

The Lewmar Synchro Block - Single Becket is engineered to deliver smooth, efficient lie handling in performance-focused sailing systems where accuracy and control are essential. Designed for racing yachts and high-performance cruisers, it combines low-friction operation with compact mechanical advantage to support demanding trimming tasks.

Single-Sheave Design with Integrated Becket

The single-sheave configuration provides a clean, direct rope path for predictable load transfer and responsive handling. An integrated becket offers a fixed termination point for all control lines, enabling efficient cascade and fine-tune systems that deliver increased mechanical advantage without adding complexity or deck clutter.

Synchro Bearing Technology

As part of Lewmar’s advanced Synchro range, the block incorporates precision technology engineered to minimise friction under load. This results in smoother trimming, faster response, and reduced effort during repeated sail adjustments, particularly valuable in high-workload or race conditions.

Marine-Grade Composite Construction

Manufactured from durable, marine-grade materials, the Synchro Block - Single Becket is built to withstand sustained loads, saltwater exposure, and frequent cycling. Robust side plates and a carefully profiled sheave ensure dimensional stability, wear resistance, and long-term reliability in demanding onboard environments.

Smooth, Dependable Performance

Optimised rope alignment and efficient load distribution promote consistent, low-friction rope flow during trimming and easing. Reduced mechanical loss helps protect running rigging from unnecessary wear while delivering accurate feedback and dependable performance throughout extended sailing programmes.

Installation & Application

Ideally suited to fine-tune controls, steady cascades, and performance-oriented deck layouts, the Lewmar Synchro Block - Single Becket integrates seamlessly into modern racing and fast-cruising setups. Its balance of precision, strength and compact efficiency makes it a professional-grade solution backed by Lewmar’s long-standing deck-hardware expertise.
